Talia Caldwell added 14 points and 11 rebounds while Gennifer Brandon also had a double-double with 12 points and 14 rebounds for the Golden Bears (15-2, 5-1). It's Cal's third win over a Top 25 team in its last five games.

UCLA was within 54-50 late in the second half when Clarendon made a 3-pointer. She later stole an inbounds pass as part of a 10-2 run then made four free throws in the final 54 seconds left to seal the win.

Thea Lemberger scored 15 points for the Bruins (13-4, 4-2). UCLA has lost two straight after winning its previous six.

Three days after topping conference-leading USC, the Bears led nearly the entire game but had to hold off a late charge by the Bruins to move atop the Pac-12 standings.

It's the latest milestone for second-year coach Lindsay Gottlieb's team. In the past two weeks Cal has beaten No. 21 Colorado and split a pair of games with No. 6 Stanford.

The win over No. 14 UCLA helped break a four-way tie for first in the Pac-12. Stanford and USC play later Sunday, with the winner joining the Bears in first.

It didn't come easily.

Cal twice blew double-digit leads in the second half and was held without a basket over the final four minutes, allowing the Bruins to make one final push.

Atonye Nyingfa made a short jumper and Markel Walker added a three-point play. Kari Korver followed with her third 3-pointer to bring UCLA within 64-60 with 1:06 left.

After Clarendon stopped the run with two free throws, the Bruins came back and pulled to 68-65 on Korver's layup with seven seconds remaining before Clarendon made two more free throws to seal the game.

Afure Jemerigbe had 10 points and four steals for Cal.

UCLA led 8-4 early before Cal went on a 20-4 run to move in front for good. Jemerigbe scored five straight points to start the run and Brittany Boyd's layup capped it and put the Bears up 24-12.

Brandon, who matched a school record with 26 rebounds in Cal's overtime win against USC on Thursday, later scored on a putback and Clarendon added a layup to make it 40-33 at the break.
